+ * Callback interface for clients interested in being notified when jobs change state.
+ * <p>
+ * A single job listener instance can be added either to the job manager, for notification
+ * of all scheduled jobs, or to any set of individual jobs.  A single listener instance should
+ * not be added to both the job manager, and to individual jobs (such a listener may
+ * receive duplicate notifications).
+ * </p><p>
+ * Clients should not rely on the result of the <code>Job#getState()</code>
+ * method on jobs for which notification is occurring. Listeners are notified of
+ * all job state changes, but whether the state change occurs before, during, or
+ * after listeners are notified is unspecified.
+ * </p><p>
